Hi Chris,
The "router" type of construction is ideal for wood and plastics.
The "mill" type of construction is ideal for metals.
Although each will, to a certain extent, do each others job it would not be ideal.
In general, home construction of a "milling machine" requires specialist machinery and knowledge so it is best to buy a mill and if necessary do the CNC conversion yourself. The "router" is relatively easy meat for home construction and requires a bit of skill but is not rocket science.
Hope this helps,
Tweakie.
